1. Each 7133 rack-mounted unit requires an air flow of 2.46 cubic meters/minute (87 CFM). When racks containing
many 7133 units are to be installed together, the following requirements must be met to ensure that the 7133
units are adequately cooled:
v The airflow is in at the front of the rack and out at the back. To avoid moving exhaust air to the intake of
another piece of equipment, racks should be positioned in alternate rows, back-to-back and front-to-front.
v The front of racks should be positioned on floor-tile seams, with a full line of perforated tiles immediately in
front of the racks. Each perforated tile should have an air flow of at least 11.34 m³/min (400 CFM). The
underfloor temperature must be at most 15°C (60°F).
v Where racks are in rows front-to-front or back-to-back, there should be a gap of at least 1220 mm (48 in)
separating the rows.
v To ensure proper air flow within each rack, the rack filler plates must be installed in unused positions. Also, all
the gaps in the front of the racks must be sealed, including the gaps between the 7133 units.
2. The recommended operating temperature is 22°C (72°F) or lower. At lower temperatures, the risk of failure in the
unit is reduced. If the operating temperature is above 22°C (72°F) for long periods of time, the unit will be
exposed to a greater risk of failure from external causes.
